MEASURING- DEVICE.

To @[5 whom it may concern:

Be it known that l, JnNs P. HANSEN, a subject of the King of Denmark, residing at Eagle, in the county of Cass and State of Nebraska, have invented certain new and useful improvements in Measuring Devices, of which the following is a specitication.

This invention relates to measuring devices and it has particular reference to a combined square, plumb-level try-square and double square adapted to be used by masons, stone-masons, carpenters, and other artisans. The invention has for its object to provide a tool of simple and etlicient construction which may be used interchangeably for a variety of purposes; and with these and other ends in view which will readily suggest themselves when the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention; it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations, and modications within the scope of the invention may be resorted to when desired.

ln the drawing- Figure 1 is a side view of a tool constructed in accordance with the invention. Fig. 2 is a sectional view taken on the plane indicated by the line .22, in Fig. 1. Fig. 2a is a sectional detail view taken on the plane indicated by the line ila-2a, in Fig. 2. Fig. 3 is a transverse sectional view taken on the plane indicated by the line 3 3, in Fig. 1. Fig. 4L is a perspective view showing one of the tubular casings detached. Fig. 5 is a perspective detail view showing one of the plugs 12 detached.

Corresponding parts in the several figures are denoted by like characters of reference.

ln the construction of the improved tool there are employed two ordinary metallic try-squares, 5-5, which are spaced apart by tubular casings, GWG, which are inserted or interposed between the limbs of the squares. rEhese tubular casings may be constructed of pieces of ordinary gas pipe of suitable dimensions to receive the spirit levels 7 which are disposed lengthwise in the tubular casings where they are held securely by means Specification of Letters Patent.

of packing rings 8, of leather, rubber.or other suitable elastic or yieldable material. The pipes constituting the tubular casings are provided intermediate their ends with notches 10, through which the position oit the air bubbles in the spirit levels may be observed; said notches being disposed in alinement with apertures 11 formed in the limbs of the try-squares. The tubular casings 6 are internally threaded at both ends for the reception of correspondingly threaded plugs 12 which serve to secure the spirit levels in position within the casings; waslr ers 9 of wood, leather, rubber' or other suit able yieldable material are interposed between the plugs 12 and the ends of the levels for the purpose or" protecting the latter against breakage. The plugs 12 are provided at their outer ends with transverse or diametrical grooves 14; registering with notches, 14a in the ends of the tubular casings for the passage of pins or bolts 15 that serve' to connect the try-squares 5 5, together, the said bolts serving the additional purpose of holding the tubular casings securely in position between the limbs of the squares. The try-squares may be connected by additional pins or bolts 16 which are preferably equipped with spacing sleeves 17 that are interposed between the llimbs of the squares for the purpose of spacing the latter suitably apart.

It will be seen from the foregoing description that the tubular casings which contain the spirit levels also serve to space the trysquares apart, said tubular casings being retained securely in position by means of the bolts 15 which latter, being placed in engagement with the diametrical grooves in the plugs 1Q will serve to lock the plugs securely in such a manner that displacement will be positively prevented.

The improved implement is provided with a diagonal bar composed of two side members 18 which are pivotally mounted upon a pin or bolt 16 near the outer end of the short limbs of the squares; said side members being connected near their outer ends by a screw or bolt 19 having a spacing sleeve 20, said screw or bolt being adjustably fitted in slots, 2Oa in the members of the diagonal bar. In the manipulation of the implement care will be taken to so adjust the pin 19 and sleeve 20 `that when the latter abuts upon the long limbs of the squares the los invention will be readily understood by those skilled in the art to which it pertains. Y The manner of using the implement will readily suggest itself to any skilled workman, and it will be seen that horizontal andV vertical ob`` servations may be simultaneously taken; it will further be evident that this improved Vimplementis capable of being utilized for a variety of purposes for which a plurality of tools have heretofore been required. VThe construction is simple and inexpensive, and the implement is compact and thoroughly convenient and ellicieiit for the which it is provided. Y Y

Having thus described the invention what is claimed is: Y A

l.. A device of the character described comprising two try-squares, tubular casings interposed between the limbs of the squares7 means for connecting the squares together, spirit levels within. theV casings, threaded plugs at the ends of said casings, and washers interposed between Vthe plugs and the ends of the ,spirit levels; said tubular casiiigs kand threaded. Yplugs being provided with slots or notches and the'limbs of the squares being provided with apertures alining with said notches; and astening members extendpui'poses igor ing through said` apertures and slots or notches;v Y Y Y Q. ln a device ofthe character described a pair of suitably connected try`squares,v tu-Y bular casings interposed between th'e'limbs of the squares',Y 'and having notched ends, spirit levels within thefcasings, threaded plugs at Vthe ends of said casings providedV and the levels; said tubular casingsand the y limbs of the squares being' provided with openings through which the le'velsniay bev observed.
